I never gave the swr on the radiator any thought. That is a good point. Hi John, it was supposed to be humorous. I find it amusing that someone will say, "I hate high SWRs.", while running a resonant dipole with an SWR of 20:1 (or whatever) on the radiating elements. Superposition and interference between the forward waves and reflected waves on the radiating elements is what brings the feedpoint impedance of a 1/2WL dipole down to 50 ohms (or whatever). If it were not for standing waves on a 1/2WL dipole, the feedpoint impedance would be in the neighborhood of 1200 ohms, similiar to an infinite dipole. -- 73, Cecil http://www.qsl.net/w5dxp |
